Answer:
Step-by-step explanation:
circumference = 2πr
2πr = 30π inches

Area = πr² = π*15*15 = 225π square inches
Answer:
a=3x+b/4-x
Step-by-step explanation:
I dont know which variable you're supposed to solve for. But here's how i got the answer above:
Divide each term in a(4-x)=3x+b by 4-x
a(4-x)/4-x=3x/4-x+b/4-x
Then, cancel the common factor of 4-x, giving you
a=3x/4-x+b/4-x
Finally, combine the numerators over the common denominator,
giving you a=3x+b/4-x
1 is 4 and 4 and 4 is 11 and 5 is 15
Answer:
It would be B because that is the only answer that contains a inequality symbol.
Step-by-step explanation:
Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results. Step 3: Determine if the remaining factors can be factored any further.
